Description

Product Description

Type OSE slam-shut valve is used to rapidly cut the gas flow during an overpressure or underpressure event. It is ideal for gas applications requiring positive shutoff protection, tight accuracy, fast speed of response, and high shock and vibration resistance. The top entry design makes in-line maintenance easy, saving time and manpower requirements.

For additional details regarding the evaluation and testing, please refer to “Blending Hydrogen with Natural Gas: Technical Factors to Consider”.

Features

  • Overpressure and Underpressure Protection
  • High Shock and Vibration Resistance – Type OSE incorporates a two-stage tripping mechanism that significantly reduces nuisance tripping caused by vibrations or inlet pressure variations commonly experienced by other shut-off valves.
  • High Accuracy – Maintains up to ±1% accuracy regardless of inlet pressure, flowrate and the size of the slam-shut.
  • Easy In-Line Maintenance – Top entry design reduces maintenance time and manpower requirements; parts can be inspected and replaced without removing the body from the line.
  • Water Tight – Type OSE is water tight to 10 ft / 3.0 m.
  • Positive Shutoff – After closing, the slam-shut valve stays closed until the system is shut down and the valve is manually reset. An O-ring on the valve plug seal provides tight shutoff.
  • Remote Alarm Capability – A limit switch is available that detects when the Type OSE slam-shut valve is tripped.

GUAGEMART’s Fisher Type OSE Slam-Shut Valves deliver fail-safe emergency shutdown performance for critical gas applications, combining rugged construction with precision-engineered sensing technology that consistently meets stringent safety standards. While maintaining competitive pricing through our optimized supply chain, we ensure rapid global delivery to minimize project downtime, backed by our 24/7 technical support team who provide expert guidance on installation, maintenance, and hydrogen service validation – because when it comes to process safety, reliability shouldn’t be compromised.
